Influencia de la longitud del recipiente y la ubicación de las sillas en los esfuerzos circunferenciales de recipientes horizontales usando el método de elementos de contorno

in this article, a stress analysis based on the 3-d boundary element method to determine the influence of the parameters:vessel length and saddles location, on the values of circumferential stress at horn of the saddles in horizontal pressure vessels on two saddles, is presented. the ntegral equation obtained for this problem includes the volume integral of the body forces, represented by self-weight of vessel. the domain integral is transformed into boundary integral using the method recommended by beer. in this work, three different saddle locations (a/r1 ratio) and five different tangent-totangent lengths of vessel are used. the numerical results obtained are compared to zick analysis, most popular method to design horizontal vessels, obtaining agreed results.
